PASTER ATTACHMENT FOR FOLDING-MACHINES.

SPECIFICATIQN forming part of Letters Patent No. 373,547, dated November 22, 1887. Application filed September 19, 1884. Serial No. 143,503. (No mndcl.)

To all whom, it may concern.-

Be it known that I, FRED WUELFING, a citizen of the United States, residing at Detroit, in the county of WVayne and State ofMichigan, have invented a new and useful Improvement in Paster Attachments for Folding-lllfachines,

. of which the following is a specification.

My invention more especially relates to that class of pasting'machines which receive the paper from a continuous roll, but is equally adaptable to all kinds of paper-folding inachines. I attain the object desired by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a top view of the machine with the upper part of the pastebox off, excepting the rollers G G. Fig. 2 is asectional view on the line a: :0, Fig. 1. Fig. 3 is a longitudinal section on the line y y, Fig. 1.

A represents the bottom part of the pastebox, which internally is cylindrical. g is a longitudinal opening on its upper side, which connects it with the top or principal receptacle, B. This top is preferably made removable. Closely filling the opening are two rollers, G G, which revolve inwardly when in motion, carrying and refining the paste from the upper into the lower receptacle of the paste-box. This lower part opens into the paste-distributer, which is cymbalshaped, formed of the disks E and F, which, when brought together, fit closely and finely at their circumferences, but leaving a hollow center, into which the paste is forced by the spiral flange fff, which revolves in the paste in the cylindrical part of the box A. The disk E is fitted onto a turned bearing on the end of the lower paste-receptacle, A, being allowed to revolve freely, and may be kept in place by the annular disk h, fastened to the end of the box A, if deemed necessary. The other part, F, of the distributer is fitted snugly but freely onto the driving-shaft O, which runs longitudinally through the center of the part A of the paste-box and receives its power through the pulley P by a belt from the folder. The disk F is secured in its place and adjusted to its component disk E by means of the feather i in the shaft 0 and the thumb-screw it through its hub. As will be seen, it can be slid away from E, for the purpose of cleaning, when necessary. As it revolves with the shalt 0 when in place for pasting, so it also carries with it the disk E more or less swiftly, and this possible variation of motions between the disks gives an additional assurance of the free flow of the paste. A slower motion is communicated to the spiral flange fff, for which purpose it is secured around a hollow shaft, D, which is made to fit-snugly but freely over the drivingshaft 0, or it might be fitted directly on the shaft if for any reason desirable. This hollow shaft extends from the inside disk, E, along the shaft 0, through a bearing in the other end of the paste-box, and far enough outside of the same to receive the gear-wheel d, which is rigidly fastened to it. It receives its slower motion through the small gear-wheel a, fastened to the driving-shaft O, which communicates with the gear-wheel b, twice its diameter, and which revolves on the rigid arm I, which is fastened to the under side of the paste-box. Fastened to the inside of this wheel b and centered on the same arm is the small gear-wheel 0, the same size as a, and which communicates motion to the gear-wheel (l, fastened to the hollow shaft D, causing it to make about one revolution to four of the shaft 0 and the pastedistributer F E. Aslower motion is also communicated to the rollers G G by means of the gear-wheel a, communicating with the gearwheel 0, (also twice its diameter,) which is fastened to the end of the shaft H, which projects from the roller G, through a bearing in the end of the paste-receptacle B, far enough for that purpose.

' Motion is communicated from the roller G to G by means of gear-wheels 0 0 0 0, rigidly fastened to the shafts of the rollers, which are secured on proper bearings on the inside of B.

J is an arm cast or fastened to the pastebox and extending around the distributer sufficiently to allow thejournal-box j of the shaft 0 to rest thereon.

K is a flange projection of the base of the pastebox for the purpose of fastening the device in its place.

I do not propose to confine myself to any particular relationship of motion between the different parts of my device, but simply indi- ICO - with the paper on the line of the fold.

The working of the device is obvious. When working, the paste in the upper part of the paste-box is passed between the rollers G G into the lower part, when it is forced by the spiral flange fffinto the space between the disks or hollow part of the distributer and constantly and uniformly distributed at the circumference. This can be so nicely regulated by my device that not one drop of paste is ever scattered or wasted, thus avoiding one of the great complaints against other machines now in use.

What I claim, and desire to secure by Letters tributer, substantially as described,and for the purposes set forth.

3. In a pasting-machine, the paste-box composed of the part A, having a rotating shaft through the center, and an opening, 9, on its upper side, in combination with the upper receptacle, B, the revolving rollers G G, and the rotating paste-distribnter F E, substantially as described, and for the purposes set forth.

4. In a pasting-machine, the paste-box composed of the part A, having a rotating shaft provided with a spiral flange through the center of the same,and the upper part, B, the re volving rollers G G, fitted to fill the opening 9 between said parts, in combination with the adjustable hollow disks or distributer E F,revolving with said shaft, all substantially as described and shown.

, 5. In a pasting-machine, a paste-box composed of two parts, A and B, provided with revolving rollers G G, fitted to fill the space or opening 9, which connects said parts, in combination with shaft H, gear-wheels e ab 0 d, arm I, driving-shaft 0, provided with a driving-pulley, P, and hollow shaft D, having a spiral flange, fff, around the same, adjustable paste-distributer EF, arm J, and bearing j,.al1 substantially as described, and for the purposes set forth.
